The 2011 Goodwood Festival of Speed kicks off at the end of the month and one of the vehicles on our "must-see" list is the Briggs Automotive Company (BAC) Mono. Making its public debut at the event, the BAC Mono is a single-seat, road-legal (in Europe), high-performance sports car that looks to just have the edge on its KTM X-Bow and Ariel Atom trackday rivals with the ability to go from 0-60 mph (96 km/h) in 2.8 seconds on the way to a top speed of 170 mph (273.6 km/h).
